BARTHOLOMEW F. KLOHS, OF CANTON, OHIO, ASSIGNOR TO THE DIEBOID SAFE 8cLOCK COMPANY, OF CANTON, OHIO, A CORPORATION OF OHIO.

IPERMUTATION-LOCK.

To all echo/m, 'it may concern:

Be it known that I, BARrI-ioLoMEw F. KLoIIs, a citizen of the UnitedStates, residing at Canton, in the county of Stark and State of Ohio,have invented certain new and useful Improvements in Permutation-Locks;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates more particularly to means for setting thecombination of permutation locks and is specifically designed to be usedin connection with doors for safes.

The particular kind or class of safe doors to which my invention isadapted for use are 'circular doors wherein time locks are to beemployed in connection with combination or permutation locks.

lVith these objects in' view the invention consists in providing deviceswhereby access can be had to the necessary parts oi' the combination orpermutation locks carried by the circular door from the periphery ofsuch circular door.

In the drawings 'forming a part of this speciiication, and in which likenumerals ot' reference indicate similar' parts, Figure l is a horizontalsection of a circular door,

the combination lock showing the rear plate removed and illustrating thebolt in locked position with reference to the lock proper. Fig. 4 is atop view of the bolt hook. Flg. 5 is a View similar to Fig. 3 showingthe Fig. 6 is a horizontal section taken on line 5--5, Fig 5. Fig. 7 isa view showing a portion oit' the entering rod, its tube and a sectionalview of the head carrying fingers, a portion of the lock body orhousing, also showing a portion of one of the tumblers and illustratingone of the rcleas ing fingers in proper relative position with referenceto the entering aperture of one of the tumblers. Fig. 8 is an end viewof the tumbler bearing or sleeve showing all ot the tumblers removed andillustrating a portion of the lock housing. Fig. 9 is a perspective`view of one of the tumblers or disks. Fig. 10 is a view showing thebolt hook rid- 5 ing disk and a spacing washer in proper Specificationof Letters Patent.

alinement therewith. Fig. 11 is a detached view of the bolt actuatingdisk. Fig. l2 is a front elevation oi5 one of the tumblers showing thesetting disk or wheel and its retaining lever and spring also showingone ol the releasing lingers properly entered and in position to releasethe holding lever. Fig. 13 is a detached perspective view ot the outermember of the door showing the lock case and its different partsproperly connected. Fig. 14 is a detachedperspective View ot' the innermember.

In the accompanying drawing, 1 represents the outer member oi the doorand 2 the inner member, which members are connected together byinterlocking lugs. The inner member 2 is provided with the chambers 3and 4t, which chambers are for the purpose of receiving the time lockand the Imrmutation or combination lock.

The combination or permutation lock housing Zl is secured to the outermember l of the door proper in tho usual manner, but' may be secured tothe inner member 2 without departing from the nature of the invention.

The outer member l is provided with the usual lock spindle 5, which lockspindle is for the purpose of actuating the various disks or tumblers inthe usual manner.

The lock housing e is provided with the usual sleeve or thimble (S uponwhich thimble the various tumblers or disks are loosely mounted, exceptthe innermost one or the disk 7, which is securely mounted upon thespindle 5, said disk being itor the purpose of actuating the bolt S bymeans oi the bolt hook 9.

The disk 7 is provided with the hub l0, which hub is ilor the purposeoit' providing a means for securely connecting the disk i to the spindle5 by means of a suitable key 1l. Upon the sleeve or thimble (3 isloosely mounted the disk l2, which disk is provided with the flange'1.3, which flange is ft'ormed of such a diameter that it will lap overthe reduced flange 144 'formed upon the disk 7. The disks 7 and l2 areeach pro vided with the notches or recesses l5 and 1G, which notches arevior the purpose of allowing the hook 17 located upon the bolt hook 9 todrop into the recesses l5 and 1G when they are brought into properalinement with the notches formed in the various disks located upon thesleeve 6, which disks will chambered disk 22 with the disk 20Y by meanset the pivoted lever 23 having teeth 24. l

It will be understood that when the lever 23 is in engagement with thedisk 2O the disks 2O and 22 will rotate in unison when' any given diskis picked up by means of the spindle. F or the purpose of holding thelever 23 in proper engagement with the diskr 2O the spring 24a isprovided, which spring normally presses the lever or holding bar 23 inproper engagement with the disk 20.

It will be understood that by pivoting the lever oi holding bar 23intermediate its ends that a rocking movement can be imparted, whichrocking movement disconnects the disk 2O from the chambered disk 22 andwhen the lever 23 is brought out of engagement with the disk 2O saiddisk 20 can be rotated so as to-chaiige the specilic combination.

The mechanism for changing the combin nation has more specific referenceto the present invention and hence it is deemed unnecessary tospecifically describe the manner of picking up the various cliainbereddisks 25 and 26, as-their construction is substant-ially the saine asAthe construction of the disks 20 and 22 together with their devices fordisconnecting and connecting the various disks including pick-up pinsthe lever or holding bar and spring. l/Vhen it is desired to change thecombination the various tumblers are picked up by the spindle in theordinary manner using the proper combination. qWhen the various tumblersare brought into position so that the not-ches 27 will be in properalinement and directly below the lateral arm 28 carried by the bolt hook9 said lateral arm is free to drop into said notches and at the sainetime the hook 17 will fall into the notches l5 and 16 and when in suchposition the apertures 29 are in such a position with reference to thereleasing lingers 30, that said releasing lingers when moved endwise ashereinafter de scribed will press against thelevers or releasing arins23 and rock said releasing arms upon their pivots 31 and disengage saidlevers from the disks 20 and while the levers 23 are thus disengaged anydesired combination can be made.

In order to provide means for operating or manipulating the fingers 30,a suitable entrance passage 32y .is provided in the 5alinement with theblock 41:

.housing isfor the purpose of holding the iiiiger head 39, to whichlinger head are adjustably attached the releasing fingers 30, whichrel-easing `ingersare adjustably attached to the head 39 by means ofsuitable i screw threads.

For the purpose of normally holding the head 39- against the outer-endof. the hous ing 38 and thereleasing Vfingers 30 out of `Contact withthe periphery of the various `chainbered disks the springs 40 areprovided,

which springs are -located between the lock `housing and the iingerliead39. When it is desired, to release the disks 2O the rod -36 is placed inthe entrance Vpassage 32 and the screw threaded` portion35 entered' vinthe screw threadedaperture 34 and rotated in the direction tomove toward`the head I39. The hollow tube 33 is connected to the housing 38,vpreferably-by screw threads land in which tube is located the Emovableblock 4l which movable block is so located with reference to a given-inger30 that its cliambeied end 42 will come over the -eX- posed end ofthe releasing finger locatedvin lWhen the block 4l is moved by means ofthe rod 36 the head 39 will together' with the releasing fingers hemoved toward the lock housing l.and when moved va sullcient distance theinner ends of the releasing lingers-will enter the .apertures 29 termedin the various vchambered disks, thereby locking the chainbered disksagainst rotation-and at the same time releasing` the various tootheddisks 20 at which time said toot-hed. .disks can be rotated independentofthe cha-inbered disks and when in this condition, the combination ycanbe changed after which. the rod 36is removed, which disconnects thcreleasing fingers and by the action of, the springs 24a and the leversor holding .arms 23 the ehambered disks and the toothed disks areauton'iatically and rotatably connected together and the combination orvpermutation lock used as before but the new combination must beemployed to releasethelockfbar 8.

For the purpose of .properly spacing-the various tumblers apart, and, atthe same time preventing the accidental rotation of any I givenchambered disk, the washers 43 are provided, which -washeisare heldagainst rotation by means ofthe lugs 44, which lugs are seated in thegrooves 45 formed in the sleeve 6. It will be understood that washerssuch as lll should be placed between all of the disks.

It will be understood that the number of teeth upon the disks 2O shouldcorrespond with the number upon the graduated dial; that is to say ifthere are a hundred numw bers upon the graduated dial there should be ahundred teeth upon the disks.

For the purpose of preventing the bolt 8 from being pushed in when thedoor is opened the bolt hook 9 is extended rearward so as to engage thelock casing il as illus- 4trated in Fig. 3.

For the purpose of providing means for connecting or assembling thedifferent parts and especially the lock bolt 8, the inner and outer doormembers are connected together by interlocking lugs, the lock bolt S andthe hollow tube 33 being carried by the outer d oor member l.. Saidparts being assembled bef'ore the door members l and 2 are lockedtogether.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent, is.-
